   TURBO-WID — projekt autorski v2 (skill: strona-autorska, 2026-07-14)
   KOTWICA WIZUALNA: wirnik turbosprężarki + stal warsztatowa.
   - Paleta: grafit/stal (ciemna CELOWO: metal, motorsport — nie „dark bo ładnie")
     + granat logo rozjaśniony do #4a8fe8 na ciemnym + mosiężne gwiazdki opinii.
   - Typografia: Big Shoulders Display (przemysł, tablice) + IBM Plex Sans/Mono.
   - PRYMITYW-SYGNATURA: linia wymiarowa z ogranicznikami + numeracja 01–08 mono.
   - Motyw: wirnik SVG w hero, wolny obrót (jedyna animacja — obroty tu ZNACZĄ);
     ukośne linie prędkości w tle hero.
   - Złamanie siatki: overlap tekstu na zdjęcie w sekcji Firma (03).
